This invention relates to a new and useful improvement in brake heads ofthat character shown in United States Letters Patent granted to Henry B.ltobischung, No. I

485,823, dated November 8, 1892. In the said Robischung patent there isa thrust block or sleeve having a corrugated reduced portion forcooperating with a spring-f pressed locking block, whereby the brakebead may be adjusted on the beam.

My resent invention contemplates the utilization of the corrugatedthrust block or sleeve, but instead of using a removable spring-pressedllocking biock, I form a serrated engagin Vsurface in the socket of thebrake head, w ich socket receives the thrust block or part of the brakebeam on which,

the brake head is mounted. rifhe socket of the brake head may he splitso that one wall thereof is movable, or said socket may be formed inpart by a hinged section. In either event, the free end of the Wall ofthe socket is provided with means whereby spring pressure may be exertedthereon for the purpose of forcing said free end invvardlj,7 and by sodoing causing the serrated engaging surface to yieldingly bear againstthe serrated surface of the tnrust block or part of the brake beam onwhich the brake face 4C from the surface 3 of the thrust brake beam, andin this instance this socket is of circular shape.

2 is a sleeve or socket of the brake beam having a reduced portion inwhich is formed 4a serrated or roughened surface 3. According to theconstruction shown in Fi l, the rear Wall of the socket in the bra ehead is formed with a serrated engaging surface 4 coperating with thesurface 3 and locking the brake head in adjusted positions on the beam.The socket of the brake head, ,shown in Fig. l, is split at 5 andprovided lwith a tongue 6 bridging the split portion, the free wallofthe socket having a lug extension 7 through which passes a bolt 8. Thehead of boit 8 is seated in one of the jaws of the brake head, and theouter end of said bolt is surrounded by a spring 9 seated in acup-shaped follower 10 against .which bears a nut ll. To remove thebrake head from the beam it is only necessary to unscrew the nutll, whenthat part of the socket Wall approximately at the point ,marked a actsas a hinge enabling the free ,end of the Socket Wall to be moved out-Nvardly so as to disengage the lookin surtblock, enabling` the brakehead to be removed from the beam or adjusted on the beam, as the casemay be. l

By screw-ing down the nut 11, after the brake head has been adjusted inproper position on the beam, it Will be noticed that ,the spring 9exerts a yielding pressure on the socket Wall and tends to support thebrake head in position, causing the thrust block to be seated againstthe forward face of the socket opening in the brake head. The directionin which the locking surface 4r is directed against the locking surface3 seas to seat the thrust block against the forward face of the socketin the brake beam is, l consider, important, as it prevents theexistence of a clearance space at this if A inattesa head is in the formlof. a separate piece having a hinge cennectio'n with the brake head.This hinge is of such construction that when the tongue 6 is out ofengagement wlth lts .5 groove, the rear wall of the socket may be lremoved laterally, but when the parts are assembled and the tongue 6 isin its seatv lateral motion of therear wall is prevented. The hingeconnection between the rear'w'all of the socket is indicated at 12 inFig. 4. It is obvious that by screwing up the nut 11 until the spring 9is made solid, or nearly so, the locking block or face will be so firmlypressed against the serrations on the sleeve that the head will berigidly held against rotation.

I am aware that minor changes in the construction, arrangement andcombination of the several partso'f my device can be made andsubstituted for' those herein Ashown and described without in the leastdeparting from the nature and principle'of my invention.
